I just fitted a Apexi Power Fc and Hc to my 95 GTST manual

It is a brand new unit

When i started the car, it is or sounds like it is not running on all the 6 cylinders

Anyone have an idea what is wrong

Thanks

If you don't have the optional boost control module then make sure that option is turned off. The default setup looks for the boost controler and will not run properly if you don't have it.

I turned it off before I started it

Even tried turning it back on to make sure I had it the right way.

The would not run more than 2 seconds with it turned on.

I have refitted the factory computer and the car is running fine.

The PFC should run the car fine out of the box,yes you do need to tune them but there set up with a base map that will run the car ok.

If it is second hand maybe the program has been changed with the Excel software and that is why the re-initialise doesn't fix it.

Check to see if the AFM settup is the correct one for your car.

Did you go throught the 20min idle time with a load on the battery.

Is the case of the unit earthed out? (read in another post where this was the issue)

The unit is brand new

I have not have enough time to play around with the settings too much

Will try on the week-end

Dose the casing on the ecu need to be touching the metal body of the car (earthed out)??

I mounted the ecu using the factory bottom ecu bracket, but it is held in and isolated from the body with the velco strips that come with the PFC

I have the stock AFM at the moment with a Apexi pod, so the it should be set to the first R33.... AFM option?

I did let is run for approx 20min, it farted and carried on a bit thuo.

Turned air cond on etc.

darrin,

had the same fault when fitting my pfc, missing on one cyl, changed back to standard ecu and running on all cyl. The fault was the main connection to the pfc not being completley home and therefore causing the miss. Check the main connection to the pfc.

Good luck.

Thanks DoubleD

Mine turned out to be the same problem

I found when you do up the bolt that holds the plug into the ECU, it causes the plug to curve at each end causing it not to make a good connection. This can also happen with factory ECU aswell

Solution- I used cable ties which went around the whole ECU and plug and pulled the plug in tight at each end. :P

Same thing has happened to me since I replied on this thread!

I was worried it was a coil or something.

Have put std ECU back in but have only had it idling so far.

Has the problem re-occured with you guy's or is it now fixed?

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
